Description

A kind of low ethanol diesel fuel of phase separation temperature
Technical field
The present invention relates to the fuel diesel that motor vehicle uses, and in particular to a kind of low ethanol diesel fuel of phase separation temperature.
Background technology
Diesel oil is the main fuel of heavy transportation machinery, farm machinery and engineering machinery, but due to diesel engine carbon black and NOx emission is higher, and the development of diesel engine is subject to restricting for increasingly stringenter environmental regulation.Design and use clean fuel is drop One of effective technology measure of low diesel engine carbon black and NOx emission.
In recent years, the utilization of renewable and clean energy resource are increasingly taken seriously, both at home and abroad to ethanol diesel fuel apply into Numerous studies are gone, have been mainly reflected in the use characteristic, combustion characteristics, fuel consumption and emission characteristic of ethanol diesel fuel, are supplying The oily time has also carried out some researchs in terms of changing the reciprocal effect to engine performance with ethanol content.Find, fire in research The ethanol diesel fuel formed is mixed with diesel oil with ethanol, it may appear that the wild effect such as low temperature phase separation, influences making for ethanol diesel fuel With, and this greatly constrains the popularization of ethanol diesel fuel.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of low ethanol diesel fuel of phase separation temperature.
The low ethanol diesel fuel of phase separation temperature of the present invention, by weight percentage, consisting of：
Ethanol 10-15%；
Emulsifying agent 5-8%, 2 are pressed by sorbester p17 and Tween 80：3 weight ratio composition；
Hexamethylene 3-6%；
Surplus is 0#Diesel oil.
The percentage by weight of each component is preferably in above-mentioned technical proposal：
Ethanol 10-12%；
Emulsifying agent 6-8%；
Hexamethylene 4-5%；
Surplus is 0#Diesel oil.
The percentage by weight of optimal each component is in above-mentioned technical proposal：
Ethanol 10%；
Emulsifying agent 6%；
Hexamethylene 4%；
Surplus is 0#Diesel oil.
The preparation method of ethanol diesel fuel of the present invention is same as the prior art, can specifically be made by the following method It is standby：By ethanol, 0#Diesel oil, emulsifying agent and hexamethylene are added sequentially in reaction kettle, stir 30-40min, are filtered, to obtain the final product.
Compared with prior art, the method have the characteristics that：The proportioning of each component is rationally designed, particularly by lipophile breast Agent and hydrophilic emulsifier are re-dubbed emulsifying agent by special proportioning, then using hexamethylene as cosolvent, make the groups such as diesel oil and ethanol / fully emulsified, so that the phase of gained finished product reaches -2 to -1 DEG C from temperature, while there is preferable efficiency of combustion (16 Alkane value is up to more than 60).
Embodiment
With reference to specific embodiment, the present invention is described in further detail, to more fully understand present disclosure, but The present invention is not limited to following embodiments.
Percentage described in following embodiment is weight percentage.
The preparation method of ethanol diesel fuel is described in following embodiment：By ethanol, 0#Diesel oil, emulsifying agent and hexamethylene are successively Be added in reaction kettle, stir 30min, filter, to obtain the final product.
Embodiment 1
Ethanol 10%；
Emulsifying agent 6%, 2 are pressed by sorbester p17 and Tween 80：3 weight ratio composition；
Hexamethylene 4%；
Surplus is 0#Diesel oil.
Embodiment 2
Ethanol 12%；
Emulsifying agent 5%, 2 are pressed by sorbester p17 and Tween 80：3 weight ratio composition；
Hexamethylene 6%；
Surplus is 0#Diesel oil.
Embodiment 3

Hexamethylene 5%；
Surplus is 0#Diesel oil.
Embodiment 4
Ethanol 10%；
Emulsifying agent 7%, 2 are pressed by sorbester p17 and Tween 80：3 weight ratio composition；
Hexamethylene 3%；
Surplus is 0#Diesel oil.
The stability of the ethanol diesel fuel as made from above-described embodiment 1-4 the methods is tested with ocular estimate, with phase Evaluation index of the separation temperature as ethanol diesel fuel stability.
Specifically evaluation method is：
It is put into after the ethanol diesel fuel prepared is sealed in Homothermal Proof Box and examines its phase separation temperature.Phenomenon of phase separation can Judged by range estimation.Using unilateral source of parallel light incidence sample, observer observes from perpendicular to the direction of incident light, and observed range is not More than 10cm；Ethanol diesel fuel with good stability is the homogeneous system of clear, if there is muddy or test tube bottom There is Observable polymer phenomenon, can think that ethanol diesel fuel system is separated.As a result as described in Table 1：
Table 1：
Take the ethanol diesel fuel as made from above-described embodiment 1-4 the methods at normal temperatures under the conditions of (10-30 DEG C), be placed in tool Stable state can be kept in plug test tube, the time that do not occur to be separated up to more than 90 days, illustrates by formula of the present invention Obtained ethanol diesel fuel has good stability.
(GB/T386- is measured to the Cetane number of the ethanol diesel fuel as made from above-described embodiment 1-4 the methods 2010), as a result as described in Table 2：
Table 2
